LAMP.

Specification of Letters 'Patent No. 27,500, dated March 13, 1860.

To all whom t may concern:

Be it known that I, ZURIEL Sworn, of' the city of Lancaster, in the State of' Pennsylvania, have invented a. new and useful Improvement in Lamps for Burning lIallow, Lard, and Oils for Illuminating Purposes; and I do declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this specification, in which- Figure l is a perspective view. Fig. 2 represents the radiating tube passing through the body of the lamp.

The nature of my invent-ion consists in placing above the flame of the lamp a` funnel connected to a tube passing down into and through the body of the lamp, and eX- tending up through the top for the purpose of radiating and conducting the heat of the flame down into the lamp to heat and melt the tallow, lard, or oils.

To enable others skilled in the art to make and use my invention I will proceed to describe the construction and operation;V reference being had to the accompanying drawings, the same letters designating like parts on each of the same figures.

In Fig. l the black lines represent the c ontour or outline of the lamp, and the dotted lines those portions of the radiating tube and of the burner or wick-holder which lie within the body of the lamp. In Fig. 2 the dotted lines represent Vthe contour or outside of the lamp and the external portions of the burner, and the black lines represent the funnel and tube throughout its whole length.

In Fig. l, A represents the body of the lamp resting upon the support B, which again rests upon the bottom D. The body A of the lamp is formed by having two concentric and parallel semicircles with space between them and joined together by a plate of metal at right angles to their edges, the top being coincident with the diameter of the semicircle. All those parts may be made of any suitable size, form and material. Upon the top of the body of the lamp is the burner or wick-holder I of an oblong form extending a little distance above the top of the lamp and any suitable distance downward within the body of the lamp. It may be made of any desirable form other than an oblong and is furnished with small apertures for inserting a pin to raise and lower the wick. On the top and at the side of the burner is an aperture used in filling the lamp with the material used for illuminating. It is furnished with a lid J which may be opened and closed at pleasure. At a suitable height above the flame is placed the funnel E which is secured to the section F of the radiating tube. This section slides and fits into the curved or bent section Gr which lies within and passes through the body of the lamp A, and upon the other eX- tremity of this latter section is fitted at (Z the section of the tube II, which also slides thereon. The funnel E and sections F and H of the tube may be removed when desired and thereby make the lamp much like an ordinary one. The extremities of the middle or bent section of the tube are a little above the top of the lamp. It is curved in a semicircular form corresponding to and concentric with the curved bottom and sides of the lamp. Any other form may be given t-o it. The first of' the section F after it leaves the funnel E is also curved to make it join with the middle section at The mode of operation of this lamp is that the heat and volatile products of combustion arising from the flame of the lamp pass into the funnel and thro-ugh the entire length of the tube, composed of the sections F G H. The heat is imparted to the tallow, &c., in the lamp.

The advantages of this lamp are that the illuminating material need not first be melted before it can be used to lill the lamp. Vithout impairing the efficiency of' the lamp, its waste heat is applied to melt the tallow, &c.7 keep it in a high temperature.

The combustion of thoroughly fluid and well-heated material in a lamp secures more perfect combustion and gives a more brilliant light. At low temperature more carbonaceous matter passes 0E unconsumed, which clogs combustion, dims the light, and is a waste of material.

This arrangement is more cleanly, protube so that the heated oil Will rise toward 10 duoes amore steady light and less smoke the flame and around the Wick, substantially than ordinary devices. as and for the purpose specified.

What I claim as my invention and desire ZURIEL SVOPE. '5 to secure by Letters Patent is Vtnesses:

Arranging the funnel E, and pipes F, G, HENRY D. MUssELMAN, and H, With such relation to the Wick tube I, WILLIAM H. SPRECKER, that heat may be taken from the flame and GEO. D. SPRECKER, passed down into the lamp under the Wick HENRY F. SPREGKER.
